Coxa valga
What is the function of the acetabular labrum in the hip joint?

Study Notes
- The hip joint is a synovial ball and socket joint.
- It consists of the acetabulum, head of femur, capsule, acetabular labrum, and 3 ligaments.
- The joint allows for flexion and extension, abduction and adduction, and medial and lateral rotation.
- Articular cartilage arrangement is thicker centrally for the head of femur and peripherally for the acetabulum.
- Coxa valga (pathological increase) can lead to decreased joint stability and decreased abductor muscles' lever arm.
- Coxa vara (pathological decrease) can lead to increased tensile stress and decreased compressive stress.
- Anteversion (pathological increase) can lead to decreased joint stability and compensatory medial rotation of the lower limb.
- Retroversion (pathological decrease) can lead to compensatory lateral rotation of the lower limb.
- The hip joint has a good range of motion but is controlled by the deep socket and ligaments.
- The joint is important for walking and weight-bearing activities.
